For a long time when I knew only the edges of this story I sort-of hoped
it was a situation where using a "secret weapon" like Lisp enabled an
average sort of person to triumph over long odds. But then I started
reading Andy Gavin's blog regularly and it's clear he's way, way, way
above average, and while he gives lots of praise to Lisp and what it
enabled, the "secret weapon" is his remarkable intelligence,
perserverence, determination, ability, etc.
I hope he blogs more about the details of GOOL, anyway!
